official treaty handbook environmental_policy_record

Curated public use: Use for the Vienna-Montreal legal and institutional architecture; treaty design is not causal proof.

Limitation: Source cards are evidence anchors, not proof that a linked claim is settled.

Source note: Consolidated official record of controls, differentiated obligations, trade, finance, reporting, and compliance architecture; it does not by itself establish causal impact.
